AUTOMOBILE-HEATER.

To a]? whom it may concern:

Be it known that we, CARL J. PaTrERsoN and OLIVER J. luLBURN, citizensof the .llnited States, residing at Jackson, in the county of Jacksonand State of Michigan, have invented certain new and useful-Improvementsin Automobile-Heaters, of which the following is a specification.

This invention relates to exhaust heaters for automobiles, and has forits object a simple construction that can be clamped over the exhaustmanifold and run into the bodyv time effectively accomplishes theheating.

In the'drawings, v Figure 1 is a side elevation of a Ford power unitshowing the heater clamped in I place.

Fig. 2 is a vertical longitudinal section of the heater.

Fig. 3 is a cross section, of the same taken on the line 3-3 of Fig. 2.v i

a designates the usual Ford cylinder block;

J) the crankcase cover,'and c the transmission. d indicates thecarbureter; e the intake manifold, and f theexhaust manifold. a:designates the so-called stove that is clamped to the manifold by theband 2 fitting ont the stud i. This stove has a flue 1 leading to thecarbureter air intake to furnish warm air to the carbureter. The intakemanifold and exhaust manifold are bolted to the cylinder block byyoke-like .clamps g.

which are threaded onto the studs 2'. These manifold clamps are quitecommon construc tion in all types of automobile engines where the twomanifolds are on the same side of the engine. Our heater comprisessimply a hood of sheet metalwhich at its forward end is bent intosinverted U-shape with one of the legs of the U considerably longer thanthe other (see Fig. 3). At the rear end the same sheet of metal is bentinto tubular form to form the pipe j. The'apron m or long leg of the Uof the forward portion is recessed at k and Z for the purpose ofstraddling the threaded studs upon which the manifold clamps engage, aswill appear from Fig. 1.

These openings straddle the two center studs. The clamps; as appearsfrom Fig. 1, are adapted to engage the metal of this depend-Specification of Letters Patent. Patented NOV. 8, 1921. Applicationfiled ianuary 10, 1921. Serial No. 436,086. 7

ing apron m on either side of the apertures k and 7, and when the nutsare screwed down air thrown from the fan and direct it into v theheater. Around the U metal sheet at the top thereof above the apron m issecured an asbestos sheet h that acts as a heat insulator. Thisfastening is accomplished by riv-t eting or spot-welding the metal sheet0 over this asbestos sheet. The pipe jis adapted to project into theinterior of the body at the junction of the dash and floor board, asindicated in Fig. 1, at one side andbelow the coil box 7).

One of thefeatures of this heater is that a simple butterfly valve (1 ismounted in the extreme end of the pipe 7' where it acts both as acontrol for the air passing through the tube and also by reason of beingat the extreme end can be used as a deflector. For instance, the heatedair can be directed toward the driver of the car or away, just asdesired, by simply turning this deflecting valve slightly.

Another important feature of this construction is that the U-likeportion of the heater also fits over the ordinary stove a: and hence theair drawn into the stove has travfold. It is, therefore, much hotter andis possible to cut down the carbureter needle valve adjustment so as tomake a material saving in gas.

\Vhat we claim is:

An exhaust heater for automobiles, comprising an open front and openbottom hood formed of a single piece of metal bent into inverted Usection with the long leg of the U arranged to run down the outside ofthe manifold forming an apron with afree bottom edge into which are cutrecesses for straddling the yoke clamp studs and permitting the yokeclamps of the manifold to enersed the entire length of the exhaustmanigage the bottom of the apron to hold the heater to the engine, thetop of the hood including the other leg of the. U being supported infree suspension above and on the inside of the manifold by the yokeclamps engaging the said apron, a reinforcing sheet of metal securedover the hood at the top and part way down both sides; and a sheet ofheat insulating material retained between such reinforcing vsheet andthe hood, the 10 In testimon whereof We aflix our si natures.
